A 9 metre Bayliner, sent out a Mayday alert when within 300 metres of the east side of the Mewstone. When found the boat was off Scabbacombe Head further to the east. The engine had failed due to fuel problems. The boat, with two on board, was towed to the visitors pontoon in Dartmouth. This was the same craft that had been towed in after a similar problem on 10 February 2011. Whilst involved with mooring this craft a second call was received..
